Where this record's text came from. faceted 2026-08 by reading the locally held text (xml); every evidence string verified as an exact substring of that text before merging. This source cites all prior work by numbered reference with no author names, so claim relations targets are described by reference number; both relations rest on explicit self-positioning sentences ('Our results ... now directly link', 'unlike the situation in our study'), and the second one names its target only in the preceding sentence ('Selective increases in single-unit activation during mental imagery of stationary stimuli have been reported ( 25 ).'). Bare citations to the fMRI reinstatement literature (refs 21-24) were deliberately not turned into relations. The paper's interpretive claim — that this reactivation is the neuronal correlate of the subjective emergence of recollection — is offered as a suggestion rather than a demonstrated mechanism, so claim type stays 'existence'. 2026-08-12 and 2026-08-15 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
2 quotations on this page contain a reference number where the paper printed a superscript. This journal style prints citations as raised numerals — parameters12,13 — and the extraction flattened them into the line, so the sentence reads parameters 12 , 13 . The digits are citation markers and not part of what the author wrote. The quotes keep them for the same reason they keep every other extraction fault: a quote is reproduced exactly or it proves nothing.
How to read this page. The article itself is not reproduced here — this paper is not cleared for redistribution, so what follows is the tag layer alone. The evidence sentences are withheld with the article. The table at the foot lists every tag the record carries; each row names the facet it belongs to, and the whose words column says whether the tag records the paper's own wording or the tagger's sentence about the paper. Every tag links to each other paper in the corpus carrying it. The machine-readable edition of the same thing is the TEI file beside this one, where the tags live in standOff, and the article is at its publisher via the link below. When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.

Tags on this paper

Every tag the record carries, each linking to every other paper in the corpus that carries it. A tag appears here whether or not its words occur in the article — the spans below are only the ones a sentence in this paper licenses. Of the 28 concept tags on this paper, none is grounded in a quoted sentence. All carry the tagger's gloss of what the term means in this paper, which is not something the article can license.

The paper

The full text is not reproduced here. This article is not cleared for redistribution, so the page carries the tag layer only. Its evidence sentences are withheld; the grounding status remains with each tag, and the article itself is at https://doi.org/10.1126/science.1164685. The reading view exists for the papers whose licence permits it.

Relations on this page carry a quotation for the claim. Where a relation was separately evidenced — and so tested against the vocabulary for its type — the row says so; none of 9 relations here carry that mark. The rest are the tagger’s reading of the sentence quoted beside them.

RETRACTED: NO RENAMING, AND THE SECOND ENDPOINT IS NOT IN THE SPAN. The edge is 'replay --renamed-across-fields--> reactivation'. The span reads: 'now DIRECTLY…' It names 'replay' and links it to FREE RECALL - not to 'reactivation', which does not appear at all. A renaming names BOTH names; this names one and relates it to a third thing.

RETRACTED: SAME FAULT, SAME PAPER, DIFFERENT ENDPOINT. The edge is 'reinstated --renamed-across-fields--> reactivation'. The span - 'the BOLD signal…' - names 'reinstated' and describes when it happens. 'reactivation' is absent. Both this and [1] point at the same missing term, which suggests the tagger had a synonym set in mind that the paper never states in one place. WHAT THE SPAN DOES SAY: that learning-period activity is reinstated at recall, measured by BOLD, with the fMRI caveat attached - a phenomenon, not a terminological equivalence, and it is already carried by other tags on this record. — strength of the relation: 0.6 — the record marks this weak · note: endpoint was 'BOLD signal', which is a measurement modality, not another NAME for the phenomenon.
